There's the rub, woofgang. You don't feel this harms other people. But I'm worried that it might.
Nobody, I would think, wants to cause unnecessary suffering to anyone. Indeed, I'd consider helping someone to end their lives under the current legislation.
I'm afraid these campaigners, like all campaigners once they get a foot in the door, will keep pushing the boundaries. That's certainly what happened in other countries. (where they now have death on demand for healthy people)
I'm sure you're a very nice person who wouldn't dream of hurting anyone for all the tea in China. Unfortunately we live in a world where people would, and very often do, 'kill their granny for a tenner'.
And there will come an unspoken pressure on elderly people 'not to be a bother'. Not to cost their family a fortune in care costs.
^Won't always be unspoken, either.
